Plumbing Repairs for Leaks, Burt Pipes, and More!
Pipes don't wait for business hours to fail, and neither do we. When a leak, burst pipe, or running toilet threatens your Sioux City home, call our after-hours emergency line at (712) 203-0950 and reach a real member of our team, day or night.
For over 120 years, Foulk Brothers Plumbing & Heating has repaired the pipes, fixtures, and water lines that keep Siouxland homes running smoothly.

24/7 Emergency Plumbing Repair When You Need It Most
Water damage doesn't pause until morning. A burst pipe can flood a basement in minutes, and a running toilet can waste hundreds of gallons before you notice the water bill. That's why we keep a dedicated emergency line open around the clock.

- Standard office line: (712) 258-3388

If you smell gas, see standing water, or hear water running where it shouldn't be, don't wait. Call our emergency number immediately and we'll walk you through what to do until help arrives.

Common Plumbing Repairs We Handle Every Day
Our technicians see the same plumbing problems again and again across Sioux City's older neighborhoods and newer subdivisions alike. We diagnose the root cause instead of just patching the symptom. Common repair calls include:
- Leaking pipes and fixtures — Slow leaks behind walls or under sinks waste water and invite mold; we track down the source fast.
- Burst pipes — Iowa winters put serious strain on plumbing, and frozen or burst pipes need immediate attention to prevent flooding.
- Pipe corrosion — Aging galvanized or copper pipes corrode from the inside out; we identify weak spots before they become emergencies.
- Running toilets — A toilet that won't stop running usually points to a worn flapper, fill valve, or flush mechanism, and it can quietly spike your water bill.
- Low water pressure — Sediment buildup, corroded pipes, or a failing pressure regulator can all leave your showers and faucets underperforming.
- Water heater issues, gas piping repairs, and fixture replacements
No matter the issue, we bring the right parts and tools the first time, so most repairs get resolved in a single visit.

Frequently Asked Questions About Plumbing Repair
What plumbing problems should I call a plumber to repair?
Common plumbing repairs include leaking pipes, dripping fixtures, running toilets, low water pressure, drain problems, damaged plumbing connections and other issues affecting your home's water or drainage systems.
How do I know if I have a hidden plumbing leak?
Signs can include unexplained increases in water usage, damp areas, water stains, musty odors, reduced water pressure or sounds of running water when fixtures aren't being used. A plumber can help locate the source of a suspected leak.
Should a leaking pipe be repaired immediately?
Yes. Even a small leak can waste water and potentially damage walls, flooring, cabinetry or other parts of the home. Addressing leaks early can help prevent a relatively minor plumbing repair from becoming a larger problem.
Do you provide plumbing repair in Sioux City and the surrounding area?
Foulk Brothers Plumbing & Heating provides residential plumbing repair throughout Sioux City and the surrounding Siouxland area. We diagnose plumbing problems and recommend repairs based on the specific issue and condition of the system.
Is it better to repair or replace an older plumbing fixture?
It depends on the fixture's age, condition, repair history and availability of replacement parts. A simple repair may restore a newer fixture, while frequently failing or outdated fixtures may be more practical to replace.
